Description

Technical Field

[0001] The invention relates to the technical field of high-temperature steam type medical sterilizers, in particular to a high-temperature steam type medical sterilizer. Background Art

[0002] High-temperature steam medical sterilizers mainly use high-temperature steam to kill various microorganisms. They have efficient and extensive sterilization effects. Their working principle is to use heating to generate steam. As the steam pressure increases, the temperature also rises. When the temperature reaches above 100°C, the steam will evaporate rapidly and form high-temperature steam. This high-temperature steam can penetrate the cell walls of microorganisms and effectively kill viruses, bacteria, fungi and other microorganisms in the cells. Medical sterilizers usually have a closed pressure sterilization pot that can maintain a certain pressure and temperature to ensure the sterilization effect.

[0003] When the existing high-temperature steam type medical sterilizer sterilizes and disinfects medical gauze or medical fabric, the medical gauze or medical fabric is directly placed into the sterilizer, and the gauze or medical fabric is steamed and sterilized by rolling. Due to the accumulation of gauze and fabric, the high-temperature steam in the sterilizer cannot penetrate the accumulated gauze and fabric, and the rolling of the inner cylinder of the sterilizer drives the gauze and fabric to turn over, which easily causes the gauze and fabric to roll up, and increases the thickness of the gauze and fabric, so that the high-temperature steam cannot completely penetrate the gauze and fabric, causing the accumulated gauze and fabric surface to be unable to be completely penetrated, steamed and sterilized by the high-temperature steam, thereby causing incomplete disinfection. At the same time, after high-temperature and high-pressure sterilization, the gauze and fabric may be taken out, which may bring risks such as thermal burns and steam burning. For this reason, we propose a high-temperature steam type medical sterilizer. Summary of the invention

[0024] During specific use, a person skilled in the art will open the sealing door 12, put medical gauze and cloth into the drum mechanism 3, and close the sealing door 12, and drive the device by starting the controller of the medical disinfection outer shell 11. At this time, the water pump in the water tank 13 is driven to transport the water source to the inside of the first steam generator 231, and the water source is heated by the first steam generator 231 to form steam after the heating. Through the continuous expansion of the steam, the steam will enter the second heater 235 of the second steam generator 234, and the steam will be heated for a second time by the second heater 235 to make the steam reach a high temperature state. At this time, the driving motor 325 is started to drive the driving motor 325 to drive the drum assembly 31 to rotate, so that the drum The component 31 drives the medical gauze and fabric to flip over. At this time, the L-shaped discharge ring 236 limits the rotation of the T-shaped steam groove 316 and transfers the steam to the steam receiving plate 315. The high-temperature steam is sprayed on the contact surface of the gauze and fabric with the steam injection plate 314 through the injection port on the inner wall of the steam injection plate 314 for disinfection.

At this time, as the limiting plate 435 leaves the limiting cylinder 412, the telescopic rod 443 on the outer wall of the mounting ring 441 continues to clamp and slide the gas delivery plate 431, so that the movable inclined block 423 at the front end of the outer wall of the threaded rod 422 slides into the internal threaded column 424, and then the telescopic drive motor 421 can drive the internal threaded column 424 to rotate, so that the internal threaded column 424 drives the main gear 439 and the adjusting gear 438 to rotate. The plastic blade 436 rotates and expands, and the output end of the telescopic rod 443 leaves the pressing groove 433 through the extension and retraction of the telescopic rod 443. The telescopic driving motor 421 continuously rotates, so that the telescopic driving motor 421 drives the auxiliary component 43 to rotate, thereby driving the plastic blade 436 to hit the gauze and fabric inside the drum frame 311 and the steam injection plate 314. At the same time, the steam discharge valve 233 is opened, so that the steam discharge valve 233 transports the high-temperature steam to the inside of the steam injection plate 314 through the steam transfer pipe 414 and the steam delivery pipe 434, and the high-temperature steam is ejected through the steam injection port 437, so that the steam injection port 437 and the injection port of the steam injection plate 314 perform double injection on the outer wall and inner wall surface of the gauze and fabric.The plastic blades 436 strike the gauze and fabrics, limiting the position of the turned gauze and fabrics to prevent them from rolling up when turning over. At the same time, the plastic blades 436 strike the gauze and fabrics, allowing the high-temperature steam to quickly diffuse on both sides of the gauze and fabrics to achieve a rapid disinfection effect. When the high-temperature steam disinfection is completed, the steam component 23 stops delivering the high-temperature steam, while the plastic blades 436 continue to strike the gauze and fabrics, allowing the gauze and fabrics to cool quickly to prevent burns when taking them out.
